Intelligent Video Surveillance for Detecting Snow and Ice Coverage on Electrical Insulators of Power Transmission Lines
One of the problems for electrical power delivery through power lines in northern countries is when snow or ice accumulates on electrical insulators. This could lead to snow or ice-induced outages and voltage collapse, causing huge economic loss. This paper proposes a novel real-time intelligent surveillance and image analysis system for detecting and estimating the snow and ice coverage on ele...
متن کاملAccretion Power in GRBs
I discuss the implication of the temporal structure of GRBs to the nature of their inner engine. I argue that the temporal strucutre shows that GRBs must involve internal shocks (or another kind of internal interaction within a relativistic outflow). To produce these internal shocks GRB inner engines must vary on a time scale of a fraction of a second and, on the other hand, they should be acti...
متن کاملWet snow hazard for power lines: a forecast and alert system applied in Italy
Wet snow icing accretion on power lines is a real problem in Italy, causing failures on high and medium voltage power supplies during the cold season. The phenomenon is a process in which many large and local scale variables contribute in a complex way and not completely understood. A numerical weather forecast can be used to select areas where wet snow accretion has an high probability of occu...
متن کاملSnow Accretion Prediction Method Using WRF Calculation Results
North part of Japan is one of the heaviest snowfall regions in winter. In a certain case, wet snow accretes to civil engineering structure such as power lines. There is a demand for the prediction that when the snow accretion will occur. General weather forecast is not enough resolution and meteorological variable for estimating snow accretion. By calculating weather condition on our own accoun...
متن کاملPower lines
In the United States, the development of biofuels has been presented as a potential way for America to become less dependent on foreign oil, while at the same time reducing greenhouse gas emissions. Both of these potential benefits are appealing, but the feasibility of biofuels, from both scientific and economic perspectives, is still an open question and much debated. In December, President Bu...
